Abstract
A cathode electrode material for use in rechargeable Li-ion batteries, based on the integration of two Li-based materials of NASICON- and Spinel-type structures, is described in the present invention. The structure and composition of the cathode can be described by a core material and a surface coating surrounding the core material, wherein the core of the cathode particle is of the formula LiMnNiO(0.5≦x≦0 & 0≦δ≦1) and having a spinel crystal structure, the surface coating is of the formula LiMTi(PO)(M: is a trivalent cation, 0.5≧x≧0) having a NASICON-type crystal structure.
